However, looking ahead, Philadelphians should brace for a slight shift in the weather. Despite the glow of today's sunshine, tonight's forecast calls for partly cloudy skies, with the low dipping around 61 degrees and the northwest wind calming to around 5 mph.

The high should be snug near 78 degrees, with a north wind rustling about at 5 mph. "New rainfall amounts of less than a tenth of an inch, except higher amounts possible in thunderstorms," the National Weather Service predicts.
As nighttime falls on Tuesday, thunderstorms might pay an early evening visit before clearing up. The sky should shift to partly cloudy with the low lurching around 62. The northwest wind will maintain a gentle pace at about 5 mph before turning calm. Wednesday heralds the return of mostly sunny skies with a high cresting near 85 degrees, providing a reprieve to the transient tumult of nature's whims. The day will carry the promise of calm winds escalating to a mild western breeze by the afternoon.
Looking towards the latter part of the week, the temperature is slated to soar, with Thursday sunny and high nearing a scorching 92 degrees. Nightfall will bring only slight relief with a partly cloudy sky and a low settling around 72. Friday pushes the envelope even further, as Philadelphia heats up to 95 degrees under mostly sunny conditions by daytime and coasts into the night under a mostly cloudy sky, with the low hovering around 71 degrees. As for the weekend, Saturday should shine with sunny rays and the high peaking at 88, while the night is forecast to be mostly clear, slinking to a low near 65 degrees.
